LTA750-10 (150°C – 850°C)

Description

Process Air Generator.  Hot air or gas generator.  It can be used with air, nitrogen, inert gases, and CO2.

Model: LTA750-10 (The plug-in voltages are 208/220V /230V/240V single phase). The power draw at 240 Volts is 10 kW, and at 208V, it is 9 kW.

Power is  10kW 50/60Hz for a 240V input. With 10 KW ~23 SCFM, air can heat to 800C (~25C input).  It may be used for Nitrogen.

Power will be  9kw 50/60Hz for a 208V input.

Temperature:  Typical use ~(40 °C – 850°C).   The temperature can be controlled with the control panel.   Power can be adjusted on the control panel. If a control panel is purchased, the flow temperature can be adjusted with flow rate (requires flow meter), power, or temperature settings. The optional control panel has contactors, phase angle SCRs, and displays for the temperature, over-temperature, and current display. The SCRs can be adjusted for the current limit.

Inlet temperature not to exceed 60°C.

Unit Description: Custom LTA Airtorch® Heavy Duty Industrial Air Heater System Model LTA750 series is an inline air heater with continuous hot air discharge up to 950°C continuous use. Outlet 2″ NPT. Inlet 1/2″ NPT male (see product images). The picture shown may be illustrative only. Outlet 2″ NPT. Inlet NPT male. The picture shows a 9″ Diameter (at flange)  and 22″ Long envelope. Pictures also show outlet and inlet, power chords, and T/C wires. Note that the unit is a plug-in with a minimum flow of 18 SCFM air (i.e., at full power).

Lower temperatures are obtained by flowing more gas or using the HIPAN/XPAN control panel described below.

Not rated for hot input beyond 60°C.   Not rated for liquid input.

Note: Parts of the surface are hotter than 50°C.    The Airtorch® has an installed  Type “K” thermocouple as a standard.

Please note that the LTA and MTA products require a flow meter or device to set the correct flow for use and ensure minimum flow. A compressed air gas source is connected to the flow meter, which regulates flow into the LTA. Please use accurate flow controls when operating above 800°C. The rated KW, voltage, or temperature should not be exceeded at any use time.

Unit Features:

• Stainless Steel Shell Construction
• Built-in Type K Thermocouple
• Lightweight with a compact, ergonomic design
• 208/220 or 230/240V plug-in design
• Rapid heat-up
• Compressed Air/Gas compatible
• Inlet gas not to exceed 60°C
• Outlet 2″ NPT. Inlet NPT male
• Inlet 1/2″ NPT.
• 1 Bar use.
• 208-240V 50/60Hz (Single phase). The wall socket must be able to supply 10 KW to the device. 240V is required for the highest temperature. Please follow local electrical codes.

Specs:

• Air Inlet: Compressed Air or Gas (DO NOT USE COMBUSTIBLE GASES) Air Outlet 2″ NPT fitting. Inlet 1/2″ NPT male.
• Weight: Lightweight with a compact, ergonomic design
• Temperature: Maximum 850°C  continuous. MHI controls are recommended if used close to the maximum temperature.
• Voltage: 208/220/230/240VAC Frequency: 50/60 Hz. The picture above is the approximate unit—dimensions:  9″Diameter (at flange)  and 22″ Long envelope.
• Power Consumption: ~ 10 KiloWatts Output Nominal@240V. when used as a plug-in for 208V, 220V, or 230V supply  the power is slightly lower.
• Power Control: The optional control panel allows you to change the airflow or the output power, varying the output temperature.
•  XPAN™ is required if power and temperature control options are required.
• Flowmeter not included. Shown as an option.
• Display – Not included- optional (HPAN and XPAN units have displays)
• The built-in Thermocouple can be linked to an external display or the control panel.
• Control panels have an ethernet socket for upload and downloads.

For users who wish for much more control and or lower than the maximum power, an XPAN Control Panel 208V/220V/240V is recommended. The units plug into the 208/230/240 V plug-in. The minimum flow for air is about 18  SCFM or higher and should be maintained. The unit should not exceed the maximum temperature of the device (note that the inlet is considered at 70°F). Please contact MHI at 513-772-0404 for panel quotes or use the pull-down menu above.

When operating close to the maximum rated temperature, it is advisable to use SCR-based controls with a rapid Overtemperature cut-off T/C (thermocouple) and the process T/C.

MHI can provide this extra T/C. Please select it in the optional menu (it is a Mandatory option as of June 2021).
